IPC: G09F9/33
Filed: 1994-02-15
Abstract: PURPOSE:To decrease the peeling of a land part and the wire breakdown of a wiring pattern to a large extent by forming the wiring pattern as a unitary body so that the pattern extends in the flowing direction of synthetic resin for insert molding with respect to the land part, to which a light emitting diodes and an electronic part are electrically connected. CONSTITUTION:A lens plate 6 is molded on a substrate 1 having the specified shape, on which light emitting diodes 2 and an electronic part 3 are mounted, as a unitary body. In this LED assembly module, a wiring pattern 5 is formed as a unitary body so that the pattern extends in the flowing direction of synthetic resin for insert molding with respect to a land part 4, to which the light emitting diodes 2 and the electronic part 3 are connected. In this way, even if the force caused by the flow of the synthetic resin is applied on the electronic part and the land is peeled by some degree, the torsional force is not applied on the wiring pattern, and the wire breakdown of the wiring pattern can be suppressed to a large extent.

Abstract: PURPOSE:To reduce disturbance by an analog TV signal without decreasing a data transmission rate. CONSTITUTION:OFDM(orthogonal frequency division multiplex modulation) symbols 41, 42 are sent at an interval of 1H. Slant line parts 43a, 43b share a frequency band in the vicinity of a video main carrier in an analog TV signal and OFDM carriers for the bands are modulated by symbols based on same data whose phases differ by 180 deg.. Analog TV signal components are cancelled to 0 by subtracting demodulated symbols of the carriers with each other and a demodulated symbol is obtained by eliminating disturbance by the analog TV signal. Furthermore, slant line parts 44a, 44b share a frequency band in the vicinity of a chrominance subcarrier and OFDM carriers for the bands are modulated by common symbols. The demodulated symbol where disturbance by the analog TV signal is eliminated is obtained by adding the demodulation symbol of the carriers.

IPC: H02M3/07
Filed: 1994-02-17
Abstract: PURPOSE:To provide an electric potential sensing circuit wherein no sensing target electric potential is affected and sensing level's dependence on power supply electric potential can be lowered. CONSTITUTION:The drain of a MOSFET T6 is applied with power supply electric potential V2, and a gate sensing target electric potential V1. To the source of MOSFET T6, a constant current circuit 12 is connected. Then, reference electric potential Vref output from a reference electric potential generating circuit 13 and the source electric potential of MOSFET T6 are compared each other by a comparison circuit 11, so that the level of sensing target electric potential is sensed. Since the electric potential is sensed. Since the sensing target sensing target electric potential V1 is applied to the gate of MOSFET T6, electric potential is sensed while the sensing target electric potential V1 is not affected. If the MOSFET T6 is operated in the region of a pentode, dependence on power supply electric potential V2 comes to be less. If the reference electric potential generating circuit 13 consists of a circuit independent of power supply electric potential V2, dependence on the power supply electric potential V2 is further reduced.

Abstract: PURPOSE: To prevent any floctuation at the beginning of a printing operation by arranging first and second optical detectors in the order of a primary light in the front position, where the primary light moving on a surface to be scanned reaches an effective scanning region, so that the optical intensity of the testing primary light may be constant.  
     CONSTITUTION: In a laser recorder, prior to the printing operation, an AO modulator 4 is supplied with the signals, which are modulated by the adjusting signals of preset intensity, so that a primary testing light is emitted to irradiate a first optical detector 11. The information of the optical intensity from the first detector 11 is fed to an automatic gain controller 14. Thus, the optical intensity of the primay testing light from the AO modulator 4 is adjusted to a preset level. Since this adjustment is accomplished each time before the scanning operations of scanning lines, the optical intensity of the primary light can always become constant on each scanning line. The primary light adjusted irradiates a second optical detector 12 so that the printing operation starting time is determined in accordance with the output.
